Inter-Switch Link Routing
235
Notice that the RSM on the 5000 series is in module 5. To configure the
RSM, we would type session 5, as shown below:
Todd5000> (enable) session 5
Trying Router-5...
Connected to Router-5.
Escape character is '^]'.
Router>en
Router#
Once we have entered the CLI of the RSM, you can see that the Router#
prompt appears just as it does on the RSFC. They are configured exactly
the same.
Creating VLANs on an RSM
Instead of creating subinterfaces as you would with an external router, you
configure each VLAN with the int vlan # command. Here is an example
of how to configure the processor to route between three VLANs:
ToddRSM#config t
ToddRSM(config)#int vlan 1
ToddRSM(config-if)#ip address 172.16.1.1 255.255.255.0
ToddRSM(config-if)#int vlan 2
ToddRSM(config-if)#ip address 172.16.2.1 255.255.255.0
ToddRSM(config-if)#int vlan 3
ToddRSM(config-if)#ip address 172.16.3.1 255.255.255.0
ToddRSM(config-if)#no shut
The interesting part of the configuration is the necessary no shutdown com-
mand for each VLAN interface. Notice in the configuration above that we
only performed a no shut on interface vlan 3. Take a look at the output of
interface vlan 2:
ToddRSM#sh int vlan 2
Vlan2 is administratively down, line protocol is down
Hardware is Cat5k RP Virtual Ethernet, address is
0030.f2c8.1138 (bia 0030.f2c8.1138)
